"As a preventative measure, Charlie Sheen has entered a rehabilitation facility," the rep said in the statement.

Through his rep, Sheen, who is currently facing charges in Aspen, Colo., over a December 25 incident where wife Brooke Mueller claimed her husband threatened her with a knife, (something he has denied), said his rehab stint will affect his job.

"He will take some time off his series 'Two and a Half Men,'" the rep's statement continued.

Sheen's rep said the actor is asking for "privacy" in light of the news.

"He has asked that his privacy be honored. No further statements are planned," the statement concluded.
